By adding `key`, this allows users to disable this shared module or they can choose to not disable this shared module (by filtering by key before disabling)
This means users can disable all shared modules if all modules are paths or attrsets with a key:
`configuration.nix`:
```nix
{ config, ... }:
{
home-manager.users.enzime = { ... }: {
disabledModules = config.home-manager.sharedModules;
};
}
```
Or disabling just this module specifically:
```nix
{ ... }:
{
home-manager.users.enzime = { ... }: {
disabledModules = [ { key = "home-manager#nixos-shared-module"; } ];
};
}
```
Or disabling all modules when you have modules you can't disable (like lambdas):
```nix
{ ... }:
{
home-manager.users.enzime = { ... }: {
disabledModules = lib.filter (v: lib.isString v || lib.isPath v || (lib.isAttrs v && v ? key)) config.home-manager.sharedModules;
};
}
```

Currently, the home-manager systemd service will only get restarted when
the home-manager configuration changes. This can lead to issues in
users' home directories not getting corrected for a while.
$ rm ~/.zshrc
$ sudo nixos-rebuild switch
$ ls ~/.zshrc
ls: cannot access '/home/enzime/.zshrc': No such file or directory
This makes it a lot easier to access the `pkgs` that would be used to
build the home configuration, e.g.
nix build ./dotfiles#homeConfigurations."user@host".pkgs.vim
This is useful as it allows access to a Nixpkgs that has been
instiantiated with config and overlays.
